Introduction to Exhaust Systems

Normal exhaust systems consist of a combination of different metallic pipes or tubes. The main function of these pipes is to ensure that the toxic gases emitted by engines during the combustion of gases are carefully let outside. In order for any vehicle to run smoothly as well as safely, it is important to make sure that the exhaust system of the vehicle is functioning properly. The most modern and latest types of exhaust systems are now fitted with technology that first cleans these gases before emitting them. Further modified systems allow for the gases to flow out in a smoother fashion, and in this way, increase the efficiency of the engine.

Power in automotive engines is generated by the burning of gases through a process known as combustion. During this process of combustion that occurs within the engine itself, certain harmful gases are released. Since these gases are poisonous and can cause harm to living being in the environment, they are first cleaned and treated when they pass through the exhaust system before being released. Another use of the exhaust system is that it reduces the noise that is usually emitted by a running engine by muffling it, thereby also reducing noise pollution.

There are four different parts that primarily make up an exhaust system- pipes, muffler, the catalytic converter, and the tail pipe. It is important for these components to work in unison in order for the gases to be emitted properly. If something goes wrong with any of these parts and the gas flow is interrupted, the performance of the engine will drastically reduce. Further, if these gases are not processed properly, they can enter the passenger section of the vehicle and cause harm to people sitting inside.

Once the gases are released during the process of combustion, these gases first reach the pipes in the exhaust. Since engines usually have more than one cylinder, this network of pipes serves to collect gases from different cylinders and collect them together before sending everything through one pipe from where, these gases are released into the environment. While the gases are formed in the engine which in the case of a car, is in the front of the vehicle, they are constantly eliminated from the back of the car because of the network of piping. These gases are constantly pushed by new gases that are formed.

Next, these gases enter the catalytic converter. The converter’s main job is to remove all harmful materials that are found in these gases. In this way, the gas that exits the converter is less harmful than the gas that entered it. Following this, it is passed through the muffler which reduces the sound emitted by the engine, before finally leaving the car through the means of a tailpipe.

Almost all exhaust systems that are pre-installed in cars can be modified to improve their performance. This can be done by reducing the amount of friction and resistance created in the exhaust system, therefore allowing the exhaust to perform faster. This will allow the gas to pass through faster which will in turn allow the engine to perform more efficiently. One way to reduce the friction would be to smoothen the insides of the pipes in the system by using specialised tools that can be found in the market.
